Usage

Redesign the management about JavaScript prototype chain inheritance,Make every instance has independent prototype chain. In other words:make inheritance like Java.

Orignal oop code:

function Parent(){
 
    var data;
 
    this.getData = functin(){
 
        return data;
 
    };
 
    this.setData(arg){
 
        data = arg;
 
    };
 
};

  
function Child(){};
 
Child.prototype = new Parent();
 
var b = new Child();
 
var c = new Child();
 
b.setData("b");
 
c.setData("c");
 
console.log("b:"+b.getData());//"b:c", incorrect
 
console.log("c:"+c.getData());//"c:c", correct

Now oop code

 const Frank = require("require");

 const Parent = Frank.buildType("Parent").classBody(function(){

   var data;

   this.getData = functin(){

       return data;

   };

   this.setData(arg){

       data = arg;

   };

}).toClass();

const Child = Frank.buildType("Child").extendsFrom(Parent).toClass();


var b = Frank.newInstance(Child);//or Child.newInstance() or new Child();

var c = Frank.newInstance(Child);//or Child.newInstance() or new Child();

b.setData("b");

c.setData("c");

console.log("b:"+b.getData());//"b:b" correct

console.log("c:"+c.getData());//"c:c" correct

Developing

const Frank = require("frank-native-core");

const SuperClass = function () {};

const Person = Frank.buildType("Person").extendsFrom(SuperClass).classBody(function () {

   this.name = Frank.FrankUtils.getter_setter();

   this.age = Frank.FrankUtils.getter_setter();

   this.job = Frank.FrankUtils.abstract4override;

   this.say = function () {

       return "I am a " + this.job() + ", " + this.name() + " , " + this.age() + " year-old.";

   };

}).toClass();

const Student = Frank.buildType("Student").extendsFrom(Person).classBody(function () {

   this.job = function () {

       return "student";

   }

}).toClass();

const Teacher = Frank.buildType("Teacher").extendsFrom(Person).classBody(function () {

   this.job = function () {

       return "teacher";

   }

}).toClass();

var student = Frank.newInstance(Student);

var teacher = Frank.newInstance(Teacher);

student.name("Tom").age(20);

teacher.name("Lili").age(30);

console.log("student.isInstance(   SuperClass)  :  " + student.isInstance(SuperClass);

console.log("student.isInstance(       Person)  :  " + student.isInstance(Person);

console.log("student.isInstance(      Student)  :  " + student.isInstance(Student);

console.log("Student.isAssignableFrom( Person)  :  " + Student.isAssignableFrom(Person);

console.log("Student.isAssignableFrom(Student)  :  " + Student.isAssignableFrom(Student);

console.log("teacher.isInstance(   SuperClass)  :  " + teacher.isInstance(SuperClass);

console.log("teacher.isInstance(       Person)  :  " + teacher.isInstance(Person);

console.log("teacher.isInstance(      Teacher)  :  " + teacher.isInstance(Teacher);

console.log("Teacher.isAssignableFrom( Person)  :  " + Teacher.isAssignableFrom(Person);

console.log("Teacher.isAssignableFrom(Teacher)  :  " + Teacher.isAssignableFrom(Teacher);

console.log("teacher.isInstance(      Student)  :  " + teacher.isInstance(Student);

console.log("teacher.isInstance(       Object)  :  " + teacher.isInstance(Object);

console.log(student.say());

console.log(teacher.say());

output logs:

student.isInstance(   SuperClass)  :  true
student.isInstance(       Person)  :  true
student.isInstance(      Student)  :  true
Student.isAssignableFrom( Person)  :  true
Student.isAssignableFrom(Student)  :  false
teacher.isInstance(   SuperClass)  :  true
teacher.isInstance(       Person)  :  true
teacher.isInstance(      Teacher)  :  true
Teacher.isAssignableFrom( Person)  :  true
Teacher.isAssignableFrom(Teacher)  :  false
teacher.isInstance(      Student)  :  false
teacher.isInstance(       Object)  :  true
I am a student, Tom , 20 year-old.
I am a teacher, Lili , 30 year-old.
